What Is GHK-Cu Face Serum?

GHK-Cu Face Serum is a lightweight copper peptide-inspired skincare step designed to fit into a daily cosmetic routine. It is usually applied after cleansing and before face cream.

In a CopperTheory routine, GHK-Cu Face Serum is designed to support hydrated-looking, smoother-looking and glowing-looking skin. It works especially well when paired with GHK-Cu Face Cream and GHK-Cu Facial Cleanser.

Why Use a GHK-Cu Face Serum?

Face serum is often the hero step in a skincare routine because it is lightweight, easy to layer and simple to use consistently. It can help give the routine a more ingredient-focused feel without making the routine complicated.

A GHK-Cu Face Serum can fit into routines focused on hydration, glow, smoother-looking skin, firmer-looking skin and a healthier-looking complexion.

1 Hydration supportUse face serum as the lightweight step in a hydrated-looking skincare routine.
2 Glowing-looking skinPair face serum with cream and weekly mask care for a fresh-looking routine.
3 Smoother-looking skinUse serum consistently as part of a simple daily skincare routine.
4 Routine foundationFace serum is one of the best starting points for copper peptide-inspired skincare.

When Should You Use GHK-Cu Face Serum?

GHK-Cu Face Serum can be used as part of a morning or evening skincare routine, depending on your lifestyle and the product directions. The simplest order is cleanser first, serum second and face cream after.

During the day, sunscreen can be used after moisturiser if that is part of your routine. At night, serum can sit between cleansing and face cream as a simple leave-on step.

How To Use GHK-Cu Face Serum in a Skincare Routine

The best way to use face serum is to keep the routine simple and repeatable. Serum should not feel like a confusing extra step. It should be the clear lightweight product that sits before moisturiser.
